embodies a'rotary body D,.hav.ing an axis of. rotation d and two or more lateral operative "bearing-poiiits aid axis d, four of said oper arranged in' different, planes roe ative bearing pointsi e,- f, g, andh,\ respec- 1 tively, beingillustrat'ed andall err rotate aroundthe-common "axis d. n the an ed to 'diversely-inclirie operative facial 35 Referring with particularity to the draw- 1 2, 3, and 4, respectively, all grou ed.

around the axis of rotation 11, and the ot or member B in the operation of the device is alternately or successively engaged with said inclined portions to produce reciprocation of one member in the rotation of the other member. The operative bearing-points e, f, g, and h are respectively embraced within the operative surface portions '1, 2, 3, and 4.

Inthe present illustration the member B: is engaged withthe member A through the instrumentality of the tension member C, whichengages alternately and jointly with theinclined portions 1 and 2 and with the in clined portions 3 and 4, the inclined portions 1 and 2 having a mutual convergence and the inclined portions 3 and 4 having a mutual convergence.

Thepeculiar formation of the 'body D causes the tension member C and the member B to be thrown back and forth or to reciprocate upon rotation of the: body D, the tension -member C moving successively over the several operative facial portions of the body D in opposition to said facial portions with said facial portions interposed between said'tension member C and the axis of rotation (1 of-the body D..

. In the. s ecific form of construction illustrated in t e drawings the rotary member A 'comprises'the stem 5 of a key finger-piece 6, and the reciprocating rnembe 'B comprises a contact-head 7, carrying contact-points 8 and 9, which are arranged to be electrically engaged with and disengaged from electrical circuit members 10 and 11.

The gspecific form and'operative arrangeinent and connection of parts and members in an embodiment of the invention in an electrical circuitmaker andbreaker such as illustrated is as follows: The key-stem and the contact-head 7 are inclosed within a tubular casing 12, from one end of which projects the key or finger-piece 6', the circuit members and 1 l ntering said casing 12 at the opposite [end of the same and being there held in place,

as at 13 and 14. The stem 5 is rotatably mounted'inthe casing and prevented from endwise. movement by internal flanges or stops 15 an'd, 16; The contact-head 7 fits slidably within the casing 12, so .as to move toward and aWa-yfrom the stem 5, and is prevented from rotary movement by being squared, the corresponding end of the casing 12 being interiorly squared to fit the contactment with t tions 3 and4 converging toward the flan e 18. Continuing around the body D, the facia portions 1, 3, 2, and 4 are arranged in the order named, and it results from the scheme of convergence of the same above described, together. with the arrangement last recited, that the said facialportions are all substantially triangular in shape, the triangular por-.

tions 1 and 2 having their bases Hand 2" merged into the flange 17 and their apices 1 and 2 merged into the flange 18 and the triangular portions 3 and 4 having their bases 3 and 4 merged into the flange 18 and their apices 3 and 4 merged into the flange 17.

.The operative bearing-points e,]', g, and h are substantially in coincidence with the apices 1 2 3 and 4', respectively. By the arrangement and formation of the facial por-' tions 1,2, 3, and 4 it is manifest that the bases 3*- and 4 extend in angular relation to the bases 1* and 2 The c0ntact-head 7 carries the tension member C, which consists of two opposed and spaced plates 19 and 20, which are held in tensional engagement with the facial portions l and 2 or 3 and 4 of the body D by springarms 21 and 22, connected with the contact head 7. The plates 19 and 20 are thus free for relative tensional movement, and the arms 21 and 22 are of proper proportions to permit the contact-head 7 to reciprocate inward of the body D as said plates 19 and 20 ride over the facial portions of said body, as will be hereinafter described.

The operation, method of use, and advantages of the improvements constituting the invention will be readily understood from the foregoing description, taken in connection with the accompanying drawings and the following statement. The

plates 19 and 20 of the tension member C constantly tend to ap-' proach each other, bearing tensionally upon the body D. With the parts and'members in the positions illustrated in the drawings the contactoints 8 and 9 are held in engagehe circuit members 10 and 11 to maintain a closed circuit, the plates 19 and 20 being in engagement or su stantiall engagement with the flange 17 and being eld in th s position by the converging portions 1 and 2 of the body D and with the base.

portions 1 and 2 of the same. If now the stem 5 be turned by the key 6 in the direc-' tion denoted by the arrow in Fig. 3, the plates 19 and 20 will be gradually forced apart, the contact-head and said plates being in'ca able of turning until the central portions 0 said plates ride onto the apices 3 and 4 or operative bearing-points g and h of the portions 3 and 4, when because of the convergence of the ortions 3 and 4 toward the bases 3 and 4 0 the same the tension of the arms 21 and.

22 will cause the plates 19 and20 to traverse the portions Sand 4 to the bases 3 and 4 of the latter and into engagement with the flange 1'8. This movement ofthe plates 19 and'20 retracts the contact-head 7 and with-,

draws the contact-points 8 and 9 from the circuit members 10 and 11', breaking the elec a artuntil' their central 'portions ride onto 1; efapicesl and 2 or'operative bearing- ""points eand fofthe portmris l and 2, When ecause oi the'convergenceio-l theportions 1 ljand 2 toward thebase's'l and 2 of the same the tension of the (arms 21 and 22 Will cause tl eplates 19 and to, traverse the portions .and'2'to thebases 1 and 2 of thelatter and {noted in dottedlines in Fi 1. It will be- 5 :noted that the traversin of the converging inclined facialportions oi" the body D by the Qt'ension member- 0 transpiresimmediately afgsqgter the latter has been subjected to the highest tension by separation of the plates 19 and '2Q,, Wh ich brings the latterplates onto tWo of 'the operativebearing-points e and f or g andflat-f HenceEthe action of the tension member in 3 5 this traversing movement and in the actua t'io'n'of the contact-head 7 is speedy, the re.- isdltantquick making and breaking of the electrical circuit being highlyadvantageous and. desirable. This traversing movement the rotation of thestem 5 and the key -6. It will also be noted-that after complete actu- -ation of the members, resulting in the movement of the contact-head into either circuitn-iaking orcircuit-breaking "position, the latter is positively locked insu'cli position by the grip of the tension member upon the body D' until the key 6 is again turned. The same 0 erative'efl'ects may be obtained by turning t e key 6 i-neither direction, as Will be manifest. Itis alsog manifest that ere the mem her B rotativelymounted and'the member A niounted for reciprocation the latter might as {operativel y be reciprocated by rotation of the former and the tension member C. The operative features of positive temporary locking and thepr'oduction of speedy phases of reciprocatory movement under the actuation of'a rotary element adapt the in'-, vention broadly to a'Wide range of uses.

Because of the peculiar formation of the body D comprised Within the member A it Will-be noted that the plates 19'and 2O trav erse the faciallportions 1, 2', 3; and 4, which are grouped around the axis (2 of rotation of posed between theplate s' 19and 2tl the 'fiiito engageinent wit'h'the flange 17., This further takes place. after and independent of the body D, with said axis of rotationbetween said plates 19 and 20, and that "the con'ijmencement of 'eac-h suoh traversing movement by the plates '19' ma zearms"; the engagement of the beai'in'gapointst'and' f or g and. h substantially atfthe ices 1 and 2" or 3 and 4" of the facial portionsl and? or3 and asueh bearing-p'omts being interaxis of rotation d. y

The 0 erative bearing-points 'e' and f being include in the operative facial portions 1 and 2, Which are at opposite sides of the plane of the axis d of the body D', and the operative}; bearing points g and 'hbeing included in the operative facial portions and j4,' which are atopposite sides of the planes of the axis dot the body D, it is'manifest' that-the "operative bearing p'oints e and g are necessarily an ranged in different planes at the sides ofsaid 8 5 axis 61 and the operative bearing points'j and h are arranged in difierent planes at the sides of'said axis (Z. The tension member (3 acts simultaneously upon the bearing-pointsyz and f in one actuation ofthe member "A 'and si- 9o multaneously upon the bearing-pointsg "and 7L in the succeeding actuation" of the member A. The plane relationof the bearing-points e, f, g, and 7t shares importance with the scheme of arrangement of the bearing-points whereby they are operatively engaged by the member B-or tension member C With such bearing-points interposed between the axis of rotation or central axis of the body D and said member B or tension member C. too

It is desired to particularly point out that especially inthe body D and the peculiar formation of the same reside the elements of novelty and efliciency concerned in the presentin'vention. Said body D has nothing in common with the characteristics of a threaded shaft or any other Well-knovvn mechanical element. It is a body'of v'aryin transverse sectional areas and angularly-d isposed smooth. operative surfaceor facial portions. The conversion ofthe motion resulting from the j oint operation and coenga ement of said body D and the member B tl iroughthe in. strumentality of the tension member 0 is caused by the peculiar action of the surface :15 or facial portions of the body D upon the,ten sion member C, and the phases of reciproca tion of the member B are instituted bythe body D alone Without the employment of any independent means for causing a reversal of motion by connecting or disconnecting op- IIO verative elements and setting up new Working adjustments. The same would be true if the body D were caused to reciprocate by rotation of the member 13., No reversing, trip r25 ping, shifting, or other equivalent means employed for changing the Working 'condb tiors at the ends of the phases of'motion 'of" the actuated .member.

wIiaving thus 'described my bodyfand the other of said members being arranged to be directly operatively engage withsaid facial portions in such arrangement that said facial portions are interposed directly between said latter member and said axis of said other member. y

2. Improved means of the character described, comprising'two members having different motion; one of said members comprising a body of varying1 transverse sectional areas and provided wit a plurality of operative relatively angularly disposed facial portions grouped about a central axis of said body; and the other of said members being arranged to be operatively engaged with said facial portions in such arrangement that said facial portions are interposed directly between said latter member and said axis of said other member. I

3. Improved means of the character described, comprising two members having different motion; one of said members comprising a body provided with a plurality of opera tive relatively angularly disposed smooth facial portions grouped about a central axis of said body; and the other of said members being arranged to be directly operatively engaged with said smooth facial portions in such arrangement that said facial ortions are interposed directly between sald latter member and said axis of said other member.

'4, Improved means of the character described, comprising a rotary member, a tension member, and areciprocating member; said tension member being connected with one of said other members, and comprising two ten-sionally relatively separable portions; and the other of said other "members being provided with a plurality of diversely-inclined operative portions with which said tension member is engaged.

In Witness whereof I have signed my name to this specification in 'the presence of two subscribing Witnesses.
